Answer:

5a. 4w+24≤100

5b. Dimensions=31ft x 19 ft

      Area = 589ft²

Step-by-step explanation:

l=w+12

p=2l+2w

p=2(w+12)+2w

p=2w+24+2w

p=4w+24

The farmer has 100ft of fencing, so maximum that the perimeter (p) can be is 100, meaning (4w+24) has to be less than or equal to 100:

4w+24≤100

For the largest possible perimeter, all 100 of fencing will be used, so allow 100 to be equal to 4w+24)

100=4w+24

4w=76

w=19ft

l=w+12

l=19+12

l=31ft

The dimensions are 31ft x 19ft.

Area=lw

=31*19

=589ft²

Write an expression that represents the perimeter of the triangle.
uysha [10]

Answer:

(3m - 2) + (2m + 7) + (5m - 3)

Step-by-step explanation:

Perimeter is found by combining all side measurements together to find the total measurement. In this case, combine the sides:

(3m - 2) + (2m + 7) + (5m - 3) is your answer.

If you need a simplified expression, simply combine all the like terms together. Like terms are terms with the same as well as same amount of variables:

(3m + 2m + 5m) + (7 - 2 - 3)

(10m) + (2)

10m + 2 is your answer.

The circumference of one coin is 8.03cm. The circumference of another coin is 0.33cm smaller. A.) what is the first step to find
Burka [1]

Answer:

Diameter of the smaller coin = 2.46 cm

Step-by-step explanation:

Circumference of a coin = 2πr

Circumference of coin A = 8.03 cm

Circumference of coin B = 8.03 cm - 0.33 cm

A.) what is the first step to find the diameter of the smaller coin?

Find the circumference of coin B

Circumference of coin B = 8.03 cm - 0.33 cm

= 7.7 cm

B.) Find the diameter of the smaller coin.

Circumference of a coin = 2πr

7.7 = 2 × 3.14 * r

7.7 = 6.28r

r = 7.7 / 6.28

r = 1.23 cm

Diameter = 2r

= 2 * 1.23 cm

= 2.46 cm

Diameter of the smaller coin = 2.46 cm
